Filed: 1960-09-27
Abstract: 962,463. Hydro-mechanical variable-speed gear. REGIE NATIONALE DES USINES RENAULT. Sept. 27, 1960 [Sept. 28, 1959], No. 33215/00. Heading F2D. A combined variable speed and differential gear for a motor vehicle comprises a hydrodynamic torque converter having an input impeller 3, turbine and reaction elements 11, 15 which latter exchange functions for forward and reverse drive, in series with first and second sun-ring planet trains 14, 30 the planet carrier 39 of the latter driving through gears 41, 42 the differential gear crown wheel 47, the torque converter and second epicyclic train being arranged on opposite sides of the differential gear. As shown, the sun and ring gears 25, 14 of the first planet train are connected to the reactor and turbine 15 and 11, respectively, and the planet carrier 28 is connected to the ring 30 of the second planet train which has a reaction sun 33. For low-speed forward one-way drive (reduced-reduced) application of the brake band 18<SP>1</SP> prevents reverse rotation of the reactor 15 and holds the sun 25. The turbine 11 drives the ring 14 of the first planet train, the carrier 28 of which drives at a reduced ratio the ring gear 30 of the second planet train. The planet carrier of the second train reacts on the sun 33 which is held against reverse rotation by a oneway detent 35 and is driven at a further reduced ratio. For two-way low-speed forward drive the sun 33 is held by a brake 36<SP>1</SP>. For two-way intermediate ratio (reduced-direct) a clutch 32 is engaged in addition to the brake 18<SP>1</SP> which former connects the sun and ring gears of the second train which upshifts to direct drive. For high ratio the brake 18<SP>1</SP> is released and the clutch 19 engaged, the clutch 32 remaining engaged, to provide a mechanical drive to the sun 25 of the first train giving overall split torque drive at near one-to-one. For reverse brakes 13<SP>1</SP> and 36<SP>1</SP> are engaged together the latter holding the sun 33 of the second train whilst the former holds the ring gear 14 and the turbine 11. The latter acts as a reactor to drive reversely the reactor 15 which drives the sun 25 of the first train reversely through a oneway detent 16, both gear trains providing reduction ratios. In Fig. 2, not shown, the first gear train precedes the torque converter and its planet carrier is connected to the impeller, its ring gear to the input and the sun gear may be braked for reduced drive or clutched to the ring gear for direct drive in the first, gear train. The clutches and brakes may be hydraulically or electromagnetically operated and a pump 8 supplies fluid pressure to a control circuit (not described).

Filed: 1969-07-02
Abstract: 1,270,714. Automatic control of paper making. INTERNATIONAL BUSINESS MACHINES CORP. July 2, 1969 [July 3, 1968], No.33303/69. Heading G3R. In a paper making process, a continuous signal, dependent on the moisture content of the paper stock produced, intermittently adjusts one process variable to maintain the moisture content at a desired value and the average value of the variable over a plurality of such adjustments controls another process variable to maximize the amount of paper produced. In a paper-making machine, Fig. 2, a mixture of pulp and liquid is deposited from outlet 204 of a headbox 202 on to an endless belt 206 which is driven by a motor 208 and carries the mixture over drying cylinders, such as 214, heated by steam from a boiler 216 so that finished paper may be wound up on a reel 212. The steam pressure applied to the drying cylinder is controlled by a valve 218 and measured by a detector 24 signals from which are applied to a controller 16 which computes what changes in speed should result in the correct degree of dryness and effects these changes intermittently by controlling motor 208. The actual degree of dryness is measured by a detector 18 signals from which are also applied to controller 16 which computes dryness error and corrects it by intermittent control of valve 218 at a frequency which is greater than that at which the speed of motor 208 is adjusted.

Patent GB-336073-A (GB)
Abstract: 336,073. Friedrichs, W. Sept. 17, 1929. Throw-out arrangements.-A franking-machine comprises a printing-roller which is rotated through a clutch thrown in owing to the collapse of toggle links, a small movement being given to the toggle joint by mechanism actuated by the passage of the article to be stamped, after which a spring completes the collapse. The links are positively returned to the position of rest, after an interval corresponding to that required for the passage of an article of normal length, by a member fixed to the printing-roller. The usual registering, locking, and die-adjusting mechanism may be provided. As shown, the articles are introduced between feed rollers 1, 2, Fig. 1, grooved to receive feelers 4 fixed to a pivot shaft 5 carrying a lever 7 adapted to oscillate a lever 9, which, in turn, rocks an arm 14 about a pivot 15. A stop arm 17 fixed to the arm 14 has a projection 18 carrying a pawl 20 the hook 21 of which engages the joint 24 of toggle links 22, 23, which, after a slight movement given to the joint 24 by the pawl 20 consequent on the passage of an article, are collapsed by a spring 26 connected to an arm 28, which is fixed to the toggle link 23 and is integral with an arm 29 normally engaging a shoulder on a disc 30 so as to hold a clutch in disengaged position. The disc 30 is thus released and the clutch rotates a printing-rolles 38 through one revolution. Consequent on the rotation of the disc 30, a stud 31 thereon engages an arm 32 integral with the pawl 20 so as to rock the latter into a position where it is clear of the toggle joint, and a stud 37 on the printing-roller 38 subsequently engages a shoulder 35 on the link 22 to return the toggles to normal position.
